Figure 5
Images of the emitted line beam from the manufactured OPA when (a) λ = 1592 nm, where \(\Delta \varphi\) was found to be 0, and (b) λ = 1548 nm, where \(\Delta \varphi\) was found to be π. (c) The cross-sections of the images shown in (a) and (b) along with a cross-section of the beam emitted from a single emitter element, i.e., a taper with Wtp = 500 nm. The measured envelope is fitted using Gaussian function approximation.
